8.02 is the second semester of the MIT introductory physics sequence. Passing the online version of this course will guarantee you an MITx certificate of mastery. The course is on electricity and magnetism which are at the heart of Maxwell's equations. We will study electric fields, magnetic fields, electromagnetic forces, conductors and dielectrics, electromagnetic waves, and the nature of light. This online version follows the MIT on-campus class as it was given by the renowned Professor Walter Lewin in the spring of 2002, and includes his video lectures and problem solving sessions.
